I am attaching two logs. I suspect that SPG lost connection to the camera. Feedback appreciated. Note that the computer also reported loss of connection with my ZWO guide camera, which was not connected as I was taking darks. I have other logs resulting from multiple restarts trying to isolate the problems. Glad to spend them if needed. Computer is Win 10 running the latest update.

Looks like this was due to an electrical storm, everything seems to be working again.
